Should-DSL: Improve readability for should-style expectations
The goal of Should-DSL is to write should expectations in Python as clear and readable as possible, using "almost" natural language (limited - sometimes - by the Python language constraints).
In order to use this DSL, you need to import
should_not objects from
>>> from should_dsl import should >>> 1 |should| equal_to(1) >>> 'should' |should| include('oul') >>> 3 |should| be_into([0, 1, 2]) Traceback (most recent call last): ... ShouldNotSatisfied: 3 is not into [0, 1, 2]
equal_to matcher verifies object equality. If you want to ensure identity, you must use
be as matcher:
>>> 2 |should| be(2)
A nice example of exceptions would be:
>>> def raise_zerodivisionerror(): ... return 1/0 >>> raise_zerodivisionerror |should| throw(ZeroDivisionError)
should has a negative version:
>>> from should_dsl import should_not >>> 2 |should_not| be_into([1, 3, 5]) >>> 'should' |should_not| include('oul') Traceback (most recent call last): ... ShouldNotSatisfied: 'should' does include 'oul'
